Abstract: A resin charged media can be a single or layered construction needled together to provide a graded-density structure of fine fibers intermixed with finer fibers. This resulting media possesses a higher particulate loading retention capability, particularly early in the filtration cycle, relative to other cellulose, spun-bonds, or other similar materials commonly applied to filtration applications where filtration is predominantly a surface-loading phenomenon. The filtration media provides for depth filtration with the multi-layered needled layers, thereby enhancing the overall particulate-holding capacity of the charged media. This results in more resistance to fine particulates and improvements in efficiency due to increased sub-micron particle loading. With the filter media consisting of a graded structure, surface loading phenomenon can be reduced and filter life improved. Since the layers in the media are physically combined using needling technology, they will not separate.

Abstract: A liquid filter apparatus, for connection to inlet and outlet piping, includes a housing which is integral with the piping and a removable integral filter unit in the housing. The integral filter unit includes bottom and top end caps with a core tube and a concentric outer tube extending between the end caps. A filter element between the core tube and the outer tube stands on ribs extending upward from the bottom end cap and is spaced from the top end cap by similar ribs extending downward from the top end cap, these ribs creating radial flow channels above and below the filter element. The filter element is a wound spiral of filter material and separator forming a plurality of axial flow channels. Some of these axial flow channels are open at the top to receive liquid from the top radial flow channel and closed at the bottom, and some of the axial channels are closed at the top and open at the bottom to discharge liquid into the bottom radial flow channel.

Abstract: A beverage stabilization process in which unstable beverages are contacted in a haze-free condition and at ambient temperature with positive-charge modified particulates, especially in the form of filter sheets, to initiate haze formation and the thus-formed haze is thereafter removed from the beverage at ambient temperature thereby resulting in the stabilization of the beverage.
